Hi,
It seems that you have broken OpenGL shaders support. Try adding
use_glshaders = false in the [main] section of the config file:
C:\Documents and Settings\HP_Administrator\Application
Data\Stellarium/config.ini

Updating the video drivers was the first thing that I did, so all I can say right now is that the current and previous ATI drivers for the X550 do not resolve the issue. As this is a legacy graphics card, driver updates are only 3 or 4 times per year at most, but I will continue to monitor.

I reported the same problem, and the "glshaders=false" completely solved the issue. The problem has apparently nothing to di with outdated videodrivers, as I used the latest ones available for my 9600 TX Radeon card.

I am experiencing the same issue. Everything looks fine on my Windows 7 laptop until I zoom in. Then the stars become squares just like the image up top. At that point my computer becomes unresoponsive and Windows closes the application. 0.10.2 does not have this issue.
